Seems to break constantly for me.
I use google Chrome Firefox Safari and IE and i'm getting the problem in all 4 browsers.
What happens is basicly i press enter nothing happens except i no longer have the typing field "targetted or highlighted" however you would say it.
Sometimes i get a wierd wierd error. only Chrome gives me this page but its basicly blueish page that's saying "oops sorry" in danish. some extra crap aswell.
Will ss it for ya the next time it happens, but this is seriously getting annoying, every time i wanna press enter i basicly gotta "Ctrl+A and Ctrl+C" before doing it. Getting very annoying after 2 weeks time...
